At Maker Labs I am a full stack developer, I write code from AWS Cloudformation templates and Kubernetes manifests right through to React JS components and mobile applications on both iOS and Android. I also code review all code written by other developers we work with and lead on most architectural decisions.I'm also responsible for implementing agile processes on the projects we work on. That means I have a lot of experience breaking projects down into user stories and making sure that those stories are reviewed by product owners and demoed at the end of each iteration. Combined with detailed code review and comprehensive test suites this allows us to deliver high quality code and quickly respond to changes in requirements.
